A Critical Assessment of the Use of Non-Human Responding Surrogates for Safety System Evaluation

摘要: The basic physical mechanisms underlying recent experimentally observed anomalous behavior in the impact performance of safety helmets evaluated with soft (human-like) and hard (magnesium alloy) headform surrogates are qualitatively quantitatively explained. principal brought to light surrogate investigation directly applicable utilization other forms (head-neck, thorax, whole body). In particular results raise a serious question as validity using non-human responding surrogates, human generated injury tolerance data, for purpose assessing system performance. implications that good crash-impact protective devices (helmut, restraints, etc. ) could be penalized and, equally important, less safe crack-impact designs result from improper assessment
